It was quite the eventful Monday in Dolphin country. As widely speculated, the Dolphins waived tight end Joey Haynos because of the foot injury he sustained against the Falcons. With Haynos out of the picture, John Nalbone would win the third tight end job by default.

His only competition now is likely a tenth offensive lineman candidate, which could steal Nalbone’s roster spot if the Dolphins decided to only carry two tight ends on the 53-man roster. Also making headlines, despite the suddenly blown up competition between Ikaika Alama-Francis and Koa Misi, was the Dolphins sending Channing Crowder, who has missed the past 13 days of practice, to get a second opinion on a leg injury Tony Sparano declined to specify.

I’m no medical expert, but usually when I hear that someone is seeking a second opinion, they didn’t like what the first doctor had to say. Sparano did say in a round about way that he isn’t “too concerned” about Crowder’s status, and reportedly remained hopeful he will still be available for the Bills in Week 1. Still though, from the sound of things, this could be more serious then we initially thought.

That means Tim Dobbins needs to step his game up if he indeed does enter the season as the starter. He hasn’t really stood out in the first three preseason games, but most of the concern about the Dolphins’ front seven centers around the lack of a pass rush and the ability to contain the edge, two things you can’t blame the inside linebackers for.

Depth-wise, the Dolphins have been cross-training Charlie Anderson a little bit, and you have to think Micah Johnon’s roster chances have improved, with Miami likely having to consider defense over special teams due to concerns behind Dansby and Dobbins.
